EXULTANCY — [Noun] The state or quality of being exultant; a triumphant, demonstrative joy. From the Latin exsultantia, from exsultare (“to leap up, exult”), from ex- (“out”) + saltare (“to leap”). Unlike contentment, which implies a quiet, satiated stillness, or elation, a more generalized buoyancy of spirit, exultancy is joy made kinetic and declarative. It is the sprinter’s leap upon breaking the tape, the stadium’s roar that shakes the girders, the champagne cork fired toward a silent boardroom ceiling—a brief, brilliant defiance of gravity before the feet must, inevitably, return to earth.
